To provide a system and method for detecting an abraded insulation inexpensively and reliably enough to eliminate the need for most of physical inspections of wires within a fuel tank of an aircraft.SOLUTION: An abraded wire detection system (AWDS) for detecting an abrasion on an insulation of a wire in a fuel tank is disclosed. The AWDS includes an electrode in contact with the fuel tank, and a current sensor in electrical series with a power source, the wire and the electrode. The current sensor includes circuitry that detects a current from the wire to the electrode, and detects an abrasion on the insulation of the wire in the fuel tank. Additionally disclosed is an aircraft having a fuel tank, a wire within the fuel tank, and the AWDS.SELECTED DRAWING: Figure 2

    【課題】航空機の燃料タンク内におけるワイヤの物理的点検のほとんどを不要にするのに十分なほど確実に、且つ安価に、摩耗した絶縁材を検出するための、システム及び方法を提供する。【解決手段】燃料タンク内のワイヤの絶縁材の摩耗を検出する、摩耗ワイヤ検出システム(AWDS)が開示される。AWDSは、燃料タンクに接触している電極と電源、ワイヤ、電極に電気的に直列に接続されている電流センサとを含む。電流センサは、ワイヤから電極への電流を検出する回路を含み、燃料タンク内のワイヤの絶縁材の摩耗を検出する。さらに開示されているのは、燃料タンクと、燃料タンク内のワイヤと、AWDSとを有する航空機である。【選択図】図2
